Ok so if The area of the square is 15 * 15. then what you need to do is subtract the total area of the 4 white sectors of a circle.
Together, the 4 sectors form one circle of radius 7.5. Now yu need to have in mind that the area of the circle they jointly form is pi * (7.5)^2. So 15 * 15 - pi * (7.5)^2 =<span>48.29
Hope this is useful</span>
Answer:
the area would be 4 inches times 4 inches, or 16 square inches.
Step-by-step explanation:
Answer:
a)4c +12 b)10x + -14 c) 3x+5 d)11y+(-1)
Step-by-step explanation:
as the nos without the variables can be added we can add the integers
The perimeter of a rectangle is twice the length plus twice the width. Thus,
2w + 2l = 36.
2l = 36 - 2w
l = 18 - w
The area is length times width.
36 = lw
36 = (18 - w)w
36 = 18w - w^2
w^2 - 18w + 36 = 0
w = (18 +- sqrt(18^2 - 4 * 36))/2
w = (18 +- sqrt(180))/2
w = 9 +- sqrt(45)
Thus, one of the side lengths is 9 + sqrt(45), and the other is 9 - sqrt(45).
